I think you mean Maung Gyi of the American Bando Association. I don't think the controversy is regards to his martial arts or fighting, but his fraudulent military service claims.
I was just at the Bando Nationals on 11 Nov 06 in Colombus, OH supporting our MT fighters. They mentioned the name "Maung Gyi" frequently there.

Fraudulent military service claims are quite common.
Do you think you can dig up some more information regarding this?

I know Vietnam has VoVinam or something...they do a demonstration at the Chinese New Year festivals here in Orlando every year...

Reminds me of some hybrid of Kung Fu and TKD...a lot of forms (a lot of XMA-esque stuff, also) and 1-step style sparring, that always ends in a flying head scissors...it's almost comical to someone who knows anything about practical arts, but the crowd always eats it up...
